My 92 Spirit will not shift out of 1st gear. I have dropped the valve body and flushed it with carb cleaner then brake clean and blew it out w/ air. I have taken the governor off and cleaned the screen and polished the valves w/ 400 grit paper, they seem to work fine. Reassembled w/ new filter and fluid. The trans will free wheel but not shift to second. It will kick back into first on acceleration. There was a small amount of debris on the magnet but not much and the old fluid did not smell burnt. This problem came on suddenly last Saturday as my son-in-law was driving home. Scratching my head!
